The optimal pH for most tissue cultures is in the range of 5.0-6.0 as at pH higher than 7. and lower than 4.5 the plant cells stop growing in cultures. pH above 6.0 gives the medium hard appearance while pH below 5.0 does not allow gelling of the medium. Thus the correct answer is option C.

Ans: In multicellular organisms, several cells are grouped to form tissues. These tissues perform particular function at a definite place in the body. For example, nerve cells from the nervous tissue which helps in transmission of messages. This is known as division of labour in multicellular organisms. Because of this division of labour.

The central nervous system ( CNS) consists of the brain and the spinal cord. It is in the CNS that all of the analysis of information takes place. The peripheral nervous system ( PNS ), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons.

There are two main types of tissues in plants: simple tissues and compound (or complex) tissues. The micrograph below shows part of a cross section of a pumpkin stem revealing some of the differences between simple and compound tissues. Figure 2 Simple tissues are generally composed of one type of cell.

Although you may not typically think of the skin as an organ, it is in fact made of tissues that work together as a single structure to perform unique and critical functions. The skin and its accessory structures make up the integumentary system, which provides the body with overall protection.
